This window frame is adapted to be installed within a window opening. Itmay be embodied in a storm window assembly or be embodied in a windowassembly of the usual type. The window frame assembly is formed entirelyof sheet metal strips. It is so constructed that when it is receivedwithin a window opening it is adjustable within limits vertically to fitthe opening. The jamb portions exhibit flanges which overlap the jambparts of a window opening. In certain figures of the drawing it is shownas associated with a window opening. The vertically slidable sash areadapted to be mounted within the frame and this application relates tothe frame assembly itself.

In the drawings, the jamb parts of a window opening are identified bythe numeral 20, the header part by the numeral 22 and the sill part bythe numeral 24. The window assembly is made up of a pair of opposedcomplementary jamb portions 26. These jamb portions are received attheir upper ends within a channelshaped downwardly open header portion28. They are received at their lower ends within an upwardly openchannel-shaped sill portion and form therewith a rectangular windowframe. The header portion 28 has its inner side Wall 29 of greater widththan its outer side wall 38 and the margin of the inner side wall isbent at an angle as at 32, Figs. 7 and 8, to facilitate insertion of asash into the header. The outer side wall of the header is folded overupon itself as at 34 between the iamb members.

Each jamb portion 26 is formed so as to eX hibit a channel-shape incross section with the open part of the channel disposed outwardlytoward the jamb parts of the window openin as shown in the drawin s.wall of the channel which is disposed outwardly of the building has agreater width than the inner wall of the channel. This outer Wall of thechannel exhibits a flange part 36 which is folded over upon itself andis adapted to overlie the ja nb part of the window opening.

The folded over linear margin of the flange of the outer side Wall ofeach channel iamb portion'laps over the adjacent end of the extendedouter side wall of the header 38, as shown particularly in Figs. 8 and9, and is secured thereto by indentations 40, as shown in Fig. '7. Suchindentations are used throughout the assembly to secure the thin sheetmetal parts together instead of employing riveting, brazing, or thelike. t is a simple and easy method of securement which has been foundparticularly suitable for this use. It is shown elsewhere in thedrawings as in Figs. 4, 6 and 11.

The opposite and inner side wall of each jamb portion has a linearmargin 42 which is folded over the adjacent end of the opposite andinner side wall 29 of the header, as shown particularly in Figs. 8 and9.

There is a supplemental header channel shown particularly in Figs. 1, 2and 7, identified as 44, which is adapted to be secured to the headerpart 22 of a window opening by nails 46 or the like. This header channel44 is designed to grippingly receive the header 28 of the frame assemblyand to permit of limited vertical adjustment of the same therein so asto accommodate the frame assembly to window openings which vary slightlyin vertical dimensions or may be somewhat uneven.

At the bottom the upwardly open channelshaped sill portion 30 has aninner side wall 48 which terminates at the end even with the bottom ofthe channel and an outer side wall 50 which extends beyond the bottom ofthe channel, as shown particularly in Fig. 5. The jamb portions of theframe 26 are seated at their lower ends within this upwardly openchannel sill member 30. The outer side of each jamb member has its flane 36. folded over the adjacent end of the outer side wall 50 of theupwardly open channel sill member 30 and secured there: to. The innerside wall of each channel jamb portion has its margin 42 folded over theadjacent end of the inner side wall of the sill member, all as shown inFig. 5,, and secured thereto by the same series of indentation-s 40 ashas heretofore been described. This seourement of the side walls of thejamb portions to the side walks of h h der han l and he pwardly opensill channel forms the rectangular window frame structure.

There s a econd sill channel member indicated as 54, shown particularlyin Fig. 3, which telescopes over the upwardly open sill member 30 andseats between the jamb portions of the window frame. The bottom of thissill member seats against the jamb face of the jamb portions. The bottomof this sill member is cut away as at 56 providing a shoulder whichseats against a lip of the jamb portion, as shown in Fig. 3. The outerside wall 58 of this downwardly open channel-shaped sill member 34 isspaced slightly from the adjacent side wall of the upwardly openchannel-shaped sill member for the purpose hereinafter described. Thesetwo channelshaped sill members make a sill portion which is box-shapedin cross section and builds up a peculiarly strong and rigid assembly.

Associated with the box-shaped sill jus't described is a. sill plate 60which is received'between the outer wall 58 of the sill member 54 andthe adjacent side wall of the sill member 3i]. The ends of this plateEll are turned over as at B2 overlapping the flange 36 of each jambportion. The lower margin of this plate 6!! is bent outwardly, as at 64,providing a lip which rests against a sill part of the window frame andwhich may be secured thereto, if desired. This sill plate is adjustablevertically with respect to the window frame between the cooperating sidewalls of the two channel-shaped sill members 36 and 54. This adjustmentcombined with the permitted adjustment within the header channel Mprovide for sufficient vertical adjustment to accommodate the frameassembly to window openings as generally found.

The channel-shaped sill member 54 is so formed as to exhibit an upwardlyextending lip 66. This upwardly extending lip is formed as acontinuation of the inner side wall E8 of the channel, as shownparticularly in Fig. 3. This lip forms a sash guide or stop extendinglengthwise along the inside of the sill.

The sill portion also includes a supplemental sill weather strip memberwhich has a downwardly open channel portion that is snugly received overthe lip 66, as shown in Figs. 3 and 4. This sill strip 10 is so shapedas to exhibit a bottom portion 12 adapted to rest upon the upper face ofthe sill. The margin of this bottom portion is bent upwardly as at 13forming a flange or lip which extends upwardly spaced from the lip 66.This supplemental sill part is removable. It is not shown in Figs. 1 and2. Its character and function are more specifically set forth andclaimed in my Patent No. 2,589,161 issued March 11, 1952.

Each jamb member is so shaped as to provide an inwardly projecting lipon its outer side identified as 14. This lip projects inwardly of thewindow frame and extends throughout the length of the jamb between thesill and the header, as shown in Figs. 1 and 2. It constitutes anextension of the outer side wall of the channel of the jamb member, asshown in Figs. 3 and 4. At the lower part of the window frame this lip74 cooperates with a flat lower guide strip 16 which is secured in placebetween the folded over margin 42 of the inner wall of each jamb channeland such inner wall, as shown particularly in Figs. 2 and 3 of thedrawings to form a sash guide channel.

At the upper part of the window frame this lip 14 cooperates with anupper guide strip 18 which is angular in cross section, as shown inFigs. 7 and 9, and which has a part 80 that is received and held betweenthe folded over margin 42 of the inner side wall of a jamb member andsuch inner wall to form a, sash guide channel. This upper guide strip isso angularly shaped as to have one portion that seats against the jambface of the jamb member and another portion that projects inwardlynormal thereto forming with the lip a sash guide channel. These upperguide strips 78 are offset transversely of the window frame with respectto the lower guide strips 16 and terminate at their lower ends spacedfrom the upper ends of the lower guide strips 16, all for purposes morespecifically set forth in the aforementioned copending application.
